Objective To establish a method for analysis of ethyl acetate and ethanol remained in lycopene oleoresin by headspace GC. Methods Ethyl acetate and aethanol remained in lycopene oleoresin were determined by headspace GC on Rtx-5 column, with FID detecter, high purity nitrogen as the carry gas, the column temperature was programmed raised. Results Ethyl acetate and ethanol were completely separated. The solvents showed good linear relationship within the concentration range examined. The recoveries were between 81%-101%. The RSD of precision was less than 5%. Conclusion This method was proved to be simple and accurate and can be used to determinate ethyl acetate and ethanol remained in lycopene oleoresin simultaneity.
